KONA 3G Installation & Operating Guide — Features

3G built-in upconverter uses a a full 10-bit path, fully motion adaptive de-interlacing, and

large multi-point digital interpolators. Downconversion uses large multi-point digital

interpolators, anti-alias filtering and interpolation.

Crossconversion is high-quality hardware-based, providing capability to streamline

dailies and offers true broadcast picture quality in realtime. Because these functions are in

hardware on the card, they are available full time, all the time—with no CPU load. Such

conversions are useful for cost effective monitoring, making standard definition dubs of

an HD project, or upconverting from a standard definition project to an HD deliverable.

KONA 3G Audio

KONA 3G supports 8-channel 24-bit 48kHz AES audio via BNC connections on the

supplied breakout cable—or with the optional K3G-Box,16-channels of AES audio.

KONA 3G’s high-quality input sample-rate conversion on AES inputs eliminates the need

for audio source synchronization. Sample rate converters auto-lock to any AES input, 32-

96kHz, and then convert it to 24-bit 48kHZ audio, locked to internal KONA 3G video.

Sample rate conversion is done at very high quality (over 120db THD).

Dual Link

KONA 3G supports Dual Link HD-SDI (4:4:4). KONA 3G supports the ingest and output of

SMPTE-372M compliant 4:4:4 RGB video and high-bandwidth 4:2:2 1080p 50, 1080p

59.94, and 1080p 60 at 10-bit.

2K Workflow Support

The KONA 3G 2K path offers potentially significant cost and labor savings over a tape-

based approach to a 2K workflow. In a unique development for customers on Mac or PC

platforms, users can go straight from telecine to disk with 2K media and eliminate steps

requiring the use of tape stock and then the digitizing of those tapes for the nonlinear

editor. 2K telecine to KONA 3G saves time and steps in the process by directly and

simultaneously creating 2K DPX files and 2K QuickTime. Material can be played out at 2K

via HSDL (High Speed Data Link), offering further synergy with other 2K products, such as

projectors or DDRs, currently available in the market.

Additionally, KONA 3G allows 2K files to be viewed on HD 1080PsF supported video

monitors, lowering the price barrier for recording to tape and viewing 2K material. This

1080 HD playout can be down-converted to SD in real time, giving the 2K DI pipeline a

powerful solution for multi-format video playout of 2K material.

By generating 2K DPX files during the digitize phase, different parts of the process (for

example, delivery of full-resolution media of shots intended for visual effects) can be

done much earlier. Offline editing can be done in Final Cut Pro 7 and with the flexibility of

Final Cut Pro 7 and QuickTime, even a 2K online is possible.

4K Mode Capture and Playout

In 4K Mode, KONA 3G offers 4K capture and playback in both YCbCr and RGB.

When using a capture application that supports 4K geometry, the 3G maps connectors

SDI1 through SDI 4 as inputs for 4K video.

When 4K playout is selected, the four SDI connectors are remapped as outputs for driving

the four quadrants of a 4K display. A large number of 4K formats are supported for this

emerging workflow; see the specifications (“Video Formats” on page 77) for supported 4K

formats.

Hardware-based Acceleration

Final Cut Pro 7 users will likely notice the DVCPROHD, HDV, and Apple RT Extreme

hardware acceleration provided by KONA 3G. This hardware acceleration was developed
